whats going on with my car.?????????????

Hi, My car is a 2000 pontiac grand prix. The problem that I am having is starting it. It will turn over but wont start. I can crank it sometimes without any problems, but after I drive it a while and shut it off it wont start again or it will shut off while driving. WHATS GOING ON??? I just replaced the battery, fuel pump fuel regulator and spark plugs. I dont know what else to do. I have heard it could be the MAF SENOR ,MAP SENSOR, IGNITION, but nobody can say for sure. Its just frustrating. SOMEBODY PLEASE HELP ME!!!!!!!!
